Memory-efficient document processing

A computing system, comprising:

• one or more processors for executing computer-readable instructions, the computer-readable instructions controlling the one or more processors to perform operations comprising:
• receiving a plurality of documents in either a first format, or in a third format that is other than the first format;
• separating each of the plurality of documents into individual pages, and creating a plurality of files, each file storing one individual page;
• individually parsing each individual page of the plurality of documents, the parsing comprising identifying a predefined set of items on each individual page, wherein the predefined set of items comprises text cells including their text content and bounding boxes, bitmap resources and their bounding boxes, and straight paths and curved paths connecting each item in the set of items;
• gathering the predefined set of items and the location of each item on each individual page of the plurality of documents into individual page files of a second format;
• and
• performing a document processing service using only the individual page files of the second format as input.

A computer program product comprising a computer-readable storage medium having program instructions embodied therewith, the program instructions executable by a processor to cause the processor to perform operations comprising:

• receiving a plurality of documents in either a first format, or in a third format that is other than the first format;
• separating each of the plurality of documents into individual pages, and creating a plurality of files, each file storing one individual page;
• individually parsing each individual page of the plurality of documents, the parsing comprising identifying a predefined set of items on each individual page, wherein the predefined set of items comprises text cells including their text content and bounding boxes, bitmap resources and their bounding boxes, and straight paths and curved paths connecting each item in the set of items;
• gathering the predefined set of items and the location of each item on each individual page of the plurality of documents into individual page files of a second format;
• and
• performing a document processing service using only the individual page files of the second format as input.
